SPECIFICATION forming part of Letters Patent No.` 532,651, dated January15, 1895.

a Application led October 17, 1893. Serial No. 488,399. (No model.) i

To all whom it may concern.-

Be it known that I, JOHN H. DYERsoN, of Kansas City, in the county ofWyandotte and State of Kansas, have invented certain new and usefulImprovements 'in'. Refrigerator- Cars, of which the following is ayfull, clear, and exact description, reference being had to theaccompanying drawings, which form a part of this specification.

My invention relates to certain new and useful improvements inrefrigerator cars and my invention consists in certain features ofnovelty hereinafter described and pointed out in the claim. A o o.

Figure I represents a section of a car taken on line I, I of Fig. III,showing my improved tanks 4in position. Fig. II represents a sectiontaken on line II, II of Fig. IV. Fig. III is a section taken on lineIII, III of Fig. I. Fig. IV is a section taken on line IV, IV of Fig.II. Fig. V is an enlarged detail view showing the overiow pipe partiallyin full lines and partially in sections. Fig. VI is an enlargedperspective view of one .of the benches for supporting the ice tanks.

Referring to the drawings: l represents a refrigerator car with myimproved refrigerating apparatus placed therein.

2 represents a series of tanks intended for holding ice for the purposeof cooling the car.

3 represents a series of iron benches having a foot piece Sasecured tothe bottom of the car as shown at 4, the Vertical arm da, the horizontalportion 4b extending laterally underv the tanks and reinforced on itsunder side by the rib Ltd, and the vertical arm 4 resting a block at theend of the car. Said benches support transversely extending angle irons5, which in turn support the ice tanks 2.

6 represents pans resting `on the bottom of the car beneath the icetanks, for the purpose of catching the drip and` water from the meltedice, the same being discharged through the bottom of the car through theusual trap 7.

The ice tanks are held in position by resting at their bottoms on theangle irons 5, being connected at the top, as shown at 8, by plates 9,having the flange 10 extending down on each side of the tops of thetanks, the plates 9 being set into the top of the car as shown at 11.The tanks are held in their position at the end of the car, by means ofa series of cross rods 12, secured at their ends to the side of the carby means of collars 13, secured by lag screws 14. Thus, by removing thelag screws, the cross rods l2 are released and the tanks 2 may bereadily removed for the purpose of cleaning, repairing, dac. The tanks 2are connected near the bottom by suitable tubes 15, whereby the watermay be drained 6o from the outside tanks to the central tank.

16 represents au overflow-pipe having perforations 17, through which thewater will pass when it has attained the height of saidl perforations,passing down through said over! flow-pipe into the pan 6; and fromthence out through the trap '7.

In order to drain the tanks at their bottom,

I providea means for raising the overflow pipe 16, which consists of alever 18, pivoted 7o to the car at 19, and having an arm 20, pivoted toa collar 2l, as Vshown at 22. Thus, by raising the lever 18, or throwingit into the position shown in dotted lines, Fig. V, the bottom of thepipe is raised above the openings 23 in a collar 24, so as to permit thewa` ter fromthe bottom of the tanks to be discharged out through saidopenings 23 into the p 25 represents plugs situated near the bot- 8o tomof the tank for the purpose of obtaining access thereto when it isdesired to clean the same. The air is caused to circulate through thetanks 2 partially by means of a pipe 26, extending along the side of thecar, to a point 8 5 near the door, where it extends across the car asshown at 27, the portion 27 having a series of perforations 2S, throughwhich the warm air passes and is conducted back through the pipes 26 tovertical portions 29 of said pipes. 9o The cold causing a vacuum, theWarmer air descends down through said pipes 29 in the interior of saidice tanks, and is cooled passing out at the lower ends of said pipesinto the body of the car, a constant circulation be- 9 5 ing thus keptup. Near the center of the end of the car, I provide an additional pipe30, having a'bell mouth 3l, which extends a short distance into theinterior of the car from the front wall of themiddle ice tank, the bellroo mouth or funnel shaped pipethus affording ready access for thewarmer air which passes down through the tank in the same manner as theside pipes, and in doing so is cooled and is discharged into the body ofthe car near its bottom. The pipes 26 are supported near the top of thecar by means of hangers 32.

33 represents blocks between the tanks and the side of the car securedto the body of the car the purpose of which is to support the tanks insuch manner as to afford ventilation and circulation of the air betweenthe tanks and the body of the car.

I claim as my invention- In a refrigerator car the combination of thebenches formed in a single piece having one foot secured to the bottomof the ear outside of the drip pan, and having the other foot resting ona block at the end of the car, an-

gle irons secured transversely on the benches, tanks for holding arefrigerant supported on the angle irons, rods extending across the carand resting in collars secured by screws to the sides of the oar andblocks between the tanks and the sides of the ear to support the tanksin such manner as to provide ventilation and circulation ot' the airbetween the tanks and the sides of the car; substantially as shown anddescribed and for the purpose set forth.
